his gold fish in the jar makes me think of the carnival game where the prize is a little goldfish. That always seem a bit inhumane to me, as I would guess that most of them don't live for very long once they're won.
I did learn something recently about how cattle ranchers keep mosquito larva out of the watering troughs by putting some goldfish in them. The fish eat the larvae and are quite fat & happy! Who knew??
